How should moist or wet biological evidence be packaged?

Moist or wet biological evidence should be packaged in paper containers to allow drying because paper is breathable and helps facilitate air circulation around the evidence, which is crucial for preventing the growth of mold and bacteria. Ensuring that the biological material can dry out prevents degradation and preserves the integrity of the evidence, making it suitable for subsequent testing and analysis.

Packaging in plastic containers or airtight jars can trap moisture, leading to contamination and deterioration of the biological material. Cardboard boxes, while better than plastic, do not provide the same level of breathability as paper containers. Therefore, using paper containers is the optimal choice for ensuring the appropriate handling and preservation of moist biological evidence.
